Description
The SHA3 digests currently  keep their internal state in a byte array which is converted to a long array for the state updates and back again after the update. This is unnecessary, conversion is only necessary during update() and final() calls.
Comments
[OpenJDK 21u] This should go to JDK 23 first. Removed the label. Also, consider not bringing it into 21 as JDK 25 is around the corner.

[jdk21u-fix-request] Approval Request from Dmitry Chuyko This is a clean backport of multi-platform SHA3 performance improvement. MessageDigests benchmarks show same C2 generated code speedup as for the original change. E.g. +25% on Graviton 2 on long arrays. The patch removes unnecessary conversions between byte arrays and long arrays without changing the computation algorithm, only code related to SHA3 is modified, except the single private->protected blockSize change in DigestBase. Testing: test/jdk/sun/security, tier1, tier2.

[~frakoczi] I think it would be useful to write a release note for this change highlighting the significant performance improvement.
